Corvettes
manufactured from 1989 to 1996 are equipped with a dual mass flywheel,
which cannot be resurfaced and must be replaced. From 1997 on, the
flywheel is the conventional solid type.
The driveline in these vehicles is unusually sensitive to vibrations.
For this reason, the flywheels are designed for fine balancing by
adding balance weights. Therefore, when replacing the flywheel, the
factory balance must be maintained. To do this, remove the existing
flywheel and place it beside the new one so both flywheels are in
the same position relative to the crankshaft dowel. Remove the existing
weight from the old flywheel and install them in the same position
on the new flywheel.
Use Loctite 262 to prevent oil leakage and torque bolts to spec.
